This study aimed to use thyme volatile oil (TVO) to control potato bacterial wilt disease caused by Ralstonia solanacearum and to explore the biochemical responses in relation to defense enzymes that induce resistance against pathogens in plants. In vitro experiments showed that all tested concentrations of TVO (1 µl, 2, 4, 6, 8, and 10 µl ml−1) significantly (P ≤ 0.05) inhibited the growth of the pathogen, with the most significant effect recorded at a concentration of 10 µl ml−1. Under greenhouse conditions, the tested concentration of TVO (10 µl ml−1) significantly (P ≤ 0.05) reduced the incidence of potato bacterial wilt and the population of R. solanacearum pathogens in potato plants. The current study also revealed that TVO (10 µl ml−1) increased the activity of antioxidant enzymes, e.g.,. peroxidase (POX) and phenylalanine ammonia-lyase (PAL), and reduced the activity of catalase (CAT) in treated potato plants. In conclusion, our results showed that TVO (10 µl ml−1) afforded a strong reduction of R. solanacearum radial growth in vitro and a high reduction in the development of potato wilt in vivo. Moreover, we demonstrated that POX and PAL activities can be used as biochemical markers for biocontrol efficacy in the control of potato bacterial wilt.

百里香油治疗可通过诱导马铃薯中的抗氧化酶活性来控制细菌性青枯病症状

这项研究旨在使用百里香挥发油(TVO)来控制由青枯雷尔菌引起的马铃薯细菌性枯萎病,并探讨与防御酶有关的生化反应,这些防御酶诱导植物对病原体的抗性在体外实验表明,TVO(1微升,2,4,6,8,和10μl毫升所有测试浓度-1)显著(P ≤0.05)抑制病原体的生长,与记录在最显著效果浓度为10 µl ml -1。下温室条件,TVO的测试浓度(10微升毫升-1)显著(P ≤0.05)降低马铃薯青枯病的发病率和人口的马铃薯中茄形青枯菌的病原体。当前的研究还表明,TVO(10 µl ml -1)可提高抗氧化酶的活性,例如。过氧化物酶(POX)和苯丙氨酸氨裂合酶(PAL),并降低了处理过的马铃薯植株中过氧化氢酶(CAT)的活性。总之,我们的结果表明,TVO(10 µl ml -1)在体外强烈抑制了青枯菌径向生长,而在体内则大大降低了马铃薯枯萎的发生。此外,我们证明了POX和PAL活性可用作控制马铃薯枯萎病的生物防治功效的生化标记。
